METAL DISK WHEEL.

To all whom it may concern:

Be it known that 1, WILLIAM Ems'rus VVILLIAMS, a citizen of the United States, and a resident. of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Metal Disk Wheels, of which the following is a specification.

The object of my invention is to obtain a disk wheel having a desirable form of rim and a desirable form of hub fastening, together with the shape of the disk which gives that greatest strength together with the greatest elasticity andprovides the most secure fastenings for the rim and the hub and also have asanitary feature in the ease of washing.

Reference will be had to the accompanying drawings in which Figure 1 is a front elevation of the wheel.

Figure 2 is a vertical sectional elevation.

Figure 3 is a front elevational detail of a part of the disk.

Figures 4: and 5 show the details of the hub nut on an enlarged scale. 1

Figure 6 shows an enlarged section on line 66 of Figure 7.

Figure 7 is a side view of a part shown in Figure 6.

Figure Sshows a position of the two parts of the rim in relation to each other when they are about to be assembled.

Figure 9 shows the end view of the nut used in fastening the rim in place.

Figure'lO is a view in the direction of the arrows 10--10 of Figure 8.

Figure 11 shows one of the rim clamping bolts.

Figure 12 is a section of one of the rim clamping bolts.

In the drawing 1 indicates the main portion of the rim of the wheel and 2 indicates the companion or bolted onflange which in conjunction with the main rim part 1 composes the rim of the wheel. 3 indicates the disk of the wheel here shown as a tapered disk and it is provided with the turned over flange a which merges into a flange 5 which is fitted to the inside of the inwardly projecting flange 6 of the main rim part 1 and the latter is provided with a terminating shoulder 7 on which the body of the disk merges from the portion 5 and is turned over at the swell 8 into the dished form of the disk that extends toward the hub.

The companion flange 2 is provided with Specification of Letters Patent.

a flange 9 which fits against a shoulder on .into these square holes by having the corners of the shanks swedged over into interlocking positions on the top and bottom sides as indicated by 15. Thus these bolts are made fast in the companion flange 2 and remain perpetually with this piece the same as if they were an integral part thereof.

In assembling the rim parts the positions of the two pieces of the rim. are indicated by Figure 8 and owing to the inclined position of the bolts 10 there must be provided an enlargement of the holes in the main rim flange 6 on the lower side thereof as is indicated by 16 and to provide for the swedged over metal which looks the bolt in place I provide the extra clearance at the top of the holes as indicated by 17.

This clearance of the bolts in the holes in the main rim flange prevents shearing strain on the bolts and allows the bolts to take up only direct pulling loads. The flange 9 mg isters on the shoulder 7 of the main rim which together with the inclined shape of the two flanges in relation to the plane of rotation of the wheel takes the registering or centering load strain in place of the bolts 10. The disk 3 is tapered as shown, being thinner at the margin and progressively thickened up to the region to where it joins the hub.

The outer face of the disk is made concave I as shown and is provided with the swell 18 which shape gives strong resistance to skid shocks and furnishes a slight degree of elasticity; From the swell 18 the disk is curved outward and terminates in a plane vertical zone 19 and it merges into an outwardly projecting flange 20 which bears on the main hub barrel at 21.- The hub is indicated by 22 and is provided with a. flange 24 located substantially in the central load line and inclined to fit the inclined surface of the disk at this point. The flange 20 and surface 21 of the hub 22 areialso slightly inclined in order to make a hub registering fit.

The vertical zone 19 of the disk is out through at intervals as is indicatedby 25 in Figure 3 in order to produce a certain degree of elasticity and bending in the fittingof the disk to the hub. I a

I provide a clamping ring 26 having an inclined bearing 27 which registers on the disk opposite the flange 24 of the huband is clamped to the disk through the medium of the round headed nuts 28 screwed on to the 20 through the spring of the parts induced by the slots 25 into a registering fitwith the hub surface 21. The nuts 28 extend into the holes '35 and register therein as against the turning movement of the disk on the bolts 29. The nuts 28 are provided with holes 36 adapted for use with a special wrench in fastening and unfastening the nuts.

The flat rounded heads of the nuts are easily washed and aid in keeping the wheel sanitary which is a desideratum.

The inclined surface of the flange 24 where it fits the disk together with the inclined fit of the flange 20 with the surface 21 of the hub insures at all times a tight registry of these parts.

The clamping ring 26 with its overlapping clamping flange 27 clampington to the body of the disk, together with the shoulder 34 of the said ring clampin on to the flange 20 of the disk secures the disk to the hub in tension strain lines as well as the registry of the disk on the hub itself provides for strut strains. v

The hub fastening as described has the'all important feature of permitting the disk to be securely and tightly fastened to the hub both in tension and strut strain lines and yet when the nuts 28 are removed the disk will be easily removed from the hub which is a great desideratum.

Demountable disks necessarily fit other parts closely and often in such a way that demounting is diflicult. In my devices, the nuts 28 having tubular shanks lying in the large bolt holes allow no lateral relative movement of the 'disk, nuts and bolts. The nuts may be easily removed separately and when removed the disk is readily removed, there being nothingwhatever to hold it.

The disk is secured to the main rim part 1 through the medium of the rivets 37 inaddition to the rim bolts 10.

The central load line of the wheel is indicated by the dotted line 38 and it will be noticed that this line'passes through the main shoulder fastening of the'hub flange 24; 1n what may be termed a neutral position WlllCh takes a direct load without putting bending strains upon the hub fastening. The in clined fit between the margin of the disk and the main rim part takesshear oil from the rivets 37 and thus permits a lesser number of those rivets fora given surface.

What I claim is:

1. In a device of the classdescribed, a rim and web of the wheel composed of a disk suitably secured tothe rim in the region outward from the central load line and dished inward crossing the central load line and then merging outward of the central load line in the fastening to the hub; in combination with a suitable hub provided with a flange having a bearing surface on the margin of the flange adapted to bear on the said disk and a bearing surface on the hub barrel adapted to bear around the central aperture of the disk and a clamping 'fiange adapted to clamp the disk to the hub through the medium of a series of bolts passing through the disk and through the clamping flange. I

2. Ina device of the class described, a suit-- able rim secured to the disk, the latter formingthe web of the wheel and a suitable hub detachably connected to the said disk, in-
